APPARATUS FOR DRYING BOBBINS.

SPECIFICATION forming part of Letters Patent No. 237,074, dated January 25, 1881.

Application filed June 21, 1880. (No model.)

To all whom at may concern:

Be it known that I, LUTHER O. BALDWIN, of Manchester, Hillsborough county, New Hampshire, have invented a new andImproved Apparatus for Drying Bobbins, of which the following is a specification.

In the manufacture of wooden bobbins it is required that the end of each be painted, and it is usual to use a quick-drying paint and lay the bobbins aside on boards to dry, arranged so that the ends shall not touch.

The object of my invention is to dispense with these boards and save the time required for handling them and the bobbins; and my invention consists of a flexible endless belt fitted with slats having concave sides adapted for receiving and carrying the bobbins. The belt is arranged to run around the frictionrolls slowly to the distance required, and the bobbins will be placed in at one end of the apparatus and discharged at the other end. Combined with the belt is a device for registering the discharge of each bobbin and keepin g a record of the number.

In the accompanying drawings, which show an apparatus embodying my invention, Figure lis asectional side elevation, and Fig. 2 is a face view, of a portion of the belt.

Similar letters of reference indicate corresponding parts.

A is the belt, which is made of flexible material and supported on the rollers a a a a, to one of which power will be applied in any desired manner to giwagslorw continuous movement of the belt around the rollers. The rollers a a are sustained in suitable supports, 1), which may be upon a suitable frame; or the lower supports may be upon the floor of a building and upper supports depend from the ceiling or, in case it is not desired to occupy the floor room, the belt may return over rollers, also suspended from the ceiling, as shown in dotted lines.

Upon the belt A are secured the lags or blocks 0, which may be made of wood or other suitable material, and secured by pins or screws, or other desired means, whereby they will be held securely. These lags c are concaved or recessed upon their sides in the direction of the width of the belt, and are placed slightly apart, so thatthe intervening spaces are of a size for receiving the bobbins snugly, as shown in Fig. 2. At the turn of the belt around the rollers the space between the lags 0 will necessarily widen, so that the bobbins may be put in at the roller a on the ascending portion of the belt, and will drop out at the roller a on the descending portion. Beneath the delivery end is fixed an inclined board, d, for receiving the bobbins as they fall from the belt, and for directing them into a suitable receptacle.

Above the delivery-board d, and at the outside of the belt A, a cross-shaft, l, is fitted in suitable bearings, which shaft will be connected with registering mechanism of any desired character. Upon this shaft there are fixed arms f, four (more or less) in number, so that there shall be one of said arms extending in the path of the ends of the bobbins that project from the side of the belt. The shaft l will thereby be given a quarter-turn by each bobbin brought down by the belt, and a register thus kept of the number discharged.

The bobbins, as they are painted, are placed in the belt, and are carried to the deliveryroller. They thus have time to dry, and are collected in the receptacle without further handling or attention.

The apparatus may be used for drying other articles than bobbins.

I have shown a board, 9, hung on the shaft c, in front of the belt, for guiding the bobbins as they pass between the belt and registering-shaft. This board may be used, it required.

The apparatus may be used to dry any articles for which it is adapted.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patcut- 1. The drying apparatus for bobbins, &c., consisting of a traveling endless belt provided with lags 0, adapted for sustaining the bobbins, substantially as shown and described.

2. In drying apparatus for bobbins, &c., the endless belt A, provided with lags or blocks 0, the supporting rollers a a, one of which is fitted for connection to power, and the delivery-board d, combined for operation, substantially as shown and described.

3. In combination with the traveling-belt A, provided with the bobbin-carriers c, the shaft Z, provided with the radial arms f, and connected with suitable registering mechanism, substantially as and for the purpose set forth.
